PUMP-ROD BOLT.

Patented April 9, 1907.

Application filed December '1, 1906. Serial No. 346,788.

Be it known that I, LEO WV. CURTIS, a citi- Zen of the United States,residing at Breckenridge, in the county of Gratiot and State ofMichigan, have invented certain new and useful Improvements in Pump-RodBolts, of which the following is a specification.

The object of my invention is to provide an improved construction ofbolt for connecting a pumphandle to the pump rod or shaft when it isdesired to pump by hand; and the invention consists in certainconstructions and arrangements of the parts hereinafter described andclaimed.

For a full understanding of the invention and the merits thereof andalso to acquire a knowledge of the details of construction of the meansfor effecting the result reference is to be had to the followingdescription and accompanying drawings, in which- Figure l is aperspective view illustrating a portion of a pump-handle andpump-rodwith my invention applied thereto. Fig. 2 is a perspective viewof my improved bolt detached and with the parts in closed position. Fig.3 is a top plan view, partly in section, the parts being shown open.Fig. 4 is a dctail view illustrating the blank from which the mainportion of thelocking-key is formed and the spring which coactstherewith.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Referring to the drawings, the numeral l designates a pump-rod which isadapted to be operated mechanically by a windmill or other means, and 2designates the pumphandle, which is intended to be disconnected from thepump-rod and swing free when the pump is being operated mechanically andwhich is also intended to be detachably connected to the pump-rodwhenever it is desired to pump by hand. For this purpose the pump-handle2 is provided with spacedapart ears 3, designed to embrace the pumprod1, and each of said ears is provided with an aperture 4, adapted toregister with the aperture in the pump-rod, so as to admit the readyinsertion of a bolt through the'register ing apertures in order toconnect the pumphandle and rod together.

My improved bolt comprises a shank 5,

said apertures, as clearly shown in Fig. l,

and to one end of said shank a key 6 is pivotally connected, the saidend of the shank being received between ears 7, projecting from one endof the key, and the said end being provided with two or moreangularly-disposed faces 5', as shown, against which a spring S bears.At the other end of the key 6 is a tongue 9, which is adapted to extendthrough an opening 10 in the shank 5, so as to lock the shank in placeas against withdrawal.

In the manufacture of my improved bolt the key portion is provided asformed out of sheet metal and stamped in the blank form` illustrated inFig. 4. The ends are then bent at about right angles to the intermediateportion 6, which forms a connecting-bar between the two ends. The endconstituting the tongue 9 is then doubled upon itself longitudinally andpreferably strengthened at its ljuncture with an inter'- mediate portion6a with one or more rivets, as shown, while the opposite end is alsodoubled upon itself, so as to form the two spacedapart members 6l) and arecess whereby to produce the ears 7 for the reception of one end of theshank 5, as above stated. The spring S is formed at one end with a lug8a, which is adapted to be inserted through an opening 6 in one end ofthe key 6, and a rivet is then passed through corresponding openings inthe said end and in the spring, so as to securely hold the spring inplace as against sidewise movement and with its free end in springengagement with the angularly-formed end 5 of the shank 5.

In the practical use of the device it is manifest that the shank 5 maybe inserted through the ears 3 and the key rocked toward the free end ofthe shank, whereupon the action of the spring S will snap the tongue 9through the opening l() in the shank 5 and securely hold the pump handleand rod connected together. No bolts or taps are used, as manifest, andit is only necw essary in order to disconnect the pumphandle andpump-rod that the key 6 be drawn outwardly, so as withdraw the tongue 9from the opening 10. The shanr 5 may then be readily drawn out.

From the foregoing description, in vconnection with the accompanyingdrawings, it

which is adapted to be inserted through the l will be seen that I haveprovided a very IOO simple form of bolt for the purpose set forth andone that may be easily applied and as easily removed.

While I have shown and described my improved pump-rod bolt as connectingthe pump-rod to a manually-operable handle, it is also manifest that itis within the purn view of my invention to use the bolt for the purposeof connecting the pump-rod to a mechanically-actuated shaft as well asto the said handle.

Having thus described the invention, what is claimed as new isl. Adevice of the character described, comprising a shank provided atone endwith an opening extending therethrough, a key pivotally connected to theother end of the bolt and provided at its free end with a tongue adaptedto extend through the opening of the shank, and a spring connected tothe said key and adapted to bear against the pivoted end of the shankand designed to press the key in a direction to snap the tongue throughthe opening in the shank.

2. A device of the character described, comprising a shank provided atone end with an opening extending therethrough and at its other endformed with angularly-disposed faces, a key provided with spacedapartears between which the angular end of the shank is pivotally mounted,said key being provided with an angularly-disposed tongue adapted toextend through the opening in the shank, and a spring secured to the keyand bearing against the angular end of the shank, as and for the purposeset forth. 3. A device of the character described, comprising a shankprovided at one end with an opening extending therethrough and formedwith angularly-disposed faces at its other end, a key provided with anintermediate portion and two ends extending laterally from theintermediate portion, one of said ends constituting a tongue adapted tobe inserted through an opening in the shank, and the other end embodyingspaced-apart members formed at one end with ears be tween which theangularly-formed end of the shank is pivotally mounted, and a spring Ssecured to the last-named end of the key with its free end bearing uponthe end of the shank, as and for the purpose set forth.

In testimony whereof l affix my signature in presence of two witnesses.
